Solar Halo Above Glendale, California

This pallid 22-degree solar halo lasted at least 20 minutes but could only be easily discerned through sunglasses, which I held over my camera lens in order to get this shot. These familiar halos result from sunlight passing through randomly oriented, hexagonal ice crystals in cirrus clouds. Photo taken about 10:30 a.m. (local time) on March 7, 2007, near Glendale, California.
